HUNTSVILLE, AL May 16, 2006 — Avocent Corporation (NASDAQ: AVCT), a leading provider of audio-visual connectivity and control solutions, today announced the addition of a new accessory for the EWMS1000 wireless media streamer, the Emerge UNI-8dB directional antenna for line-of-sight extended distance capability. The Avocent directional antenna provides extended range operation by focusing the energy of the antenna signal into an intensified unidirectional beam. In line-of-sight applications the directional antenna allows the wireless media streamer receiver to be placed up to 1000 feet from the transmitter. Applications requiring extended distance benefit from using the directional antenna as it allows the user to install a display system without running wires around a room, or incur the expense of having to open walls to run conduit.

The Avocent Emerge UNI-8dB directional antenna package comes with two antennas, one antenna for the EWMS1000 transmitter, and a second antenna for the EWMS1000 receiver. The antennas work in the 802.11a band and provide frequency ranges of 5.150 GHz to 5.825 GHz. Standard delivery of the Emerge EWMS1000 wireless media streamer includes factory-equipped omni-directional antennas which provide signal transmission of up to 300 feet line-of-sight.

“The new directional antenna provides users the needed support for extended distance that is required in many digital signage applications,” said Mitch Friend, senior vice president and general manager of Avocent. “As an industry leader in wireless video extension technology, we are pleased to bring this option to the professional audio-visual market. Our goal is to provide solutions that will ultimately render savings in installation costs and simplify connectivity.”

The Emerge EWMS1000 wireless media streamer can be deployed in either a point-to-point (extension) or point-to-multipoint (broadcast) configuration. It delivers full motion streaming video and audio to multiple display devices, and provides support for multiple input/output formats including Component, S-Video, Composite Video, VGA computer video (640 x 480), RS-232 control, and stereo audio.

Demonstrations of the Avocent Emerge UNI-8dB directional antenna will take place in the Avocent booth (#1619) at Digital Retailing Expo, in Rosemont, IL, May 17-18.
